Coronavirus – ‘Strong evidence’ that the virus is airborne
SARS-CoV-2, the virus which causes the coronavirus disease (Covid-19), is predominantly transmitted through the air, according to a new study published in The Lancet journal. “There is consistent, strong evidence that SARS-CoV-2 spreads by airborne transmission. Although other routes can contribute, we believe that the airborne route is likely to be dominant. The public health community should act accordingly and without further delay,” according to the analysis from UK, US and Canada.
The study also concludes that asymptomatic or pre – symptomatic transmission of the virus from people, who were not coughing or sneezing may account for at least a third of cases which may also go up to 59 percent of global transmissions, supports the hypothesis that SARS-CoV-2 is primarily in airborne mode of transmission.
The authors of the paper say that compared to outdoors, SARS-CoV-2’s transmission is higher indoors and is substantially reduced by indoor ventilation. These observations, the study says, support a predominantly airborne route of transmission.
At last, the study concluded that there was consistent, strong evidence that SARS-CoV-2 spreads by airborne transmission. “Although other routes can contribute, we believe that the airborne route is likely to be dominant.”
